Gas Monitoring System

The gas monitoring system is an intelligent system for real-time detection, analysis and recording of gas composition and concentration in the environment. Including various high-temperature gases, flammable gases, toxic gases, industrial waste gas, dust, temperature and humidity, etc.

It is widely used in industrial safety, environmental protection, petrochemical, energy production and other fields to ensure safe, compliant and efficient operation.

Sino-Inst’s portable gas detectors can monitor and control exhaust emissions, air pollution, and gas concentrations in industrial production, urban environments, and agricultural greenhouses. It can accurately capture small changes in gas concentrations in real time, thereby promptly detecting potential safety hazards.

Components of the Gas Monitoring System

Commonly used gas monitoring systems basically have similar system structures. For example, VOCS exhaust gas monitoring system, methane/oxygen/hydrogen sulfide gas online monitoring system, nitrogen oxide online detection system, greenhouse gas online monitoring system, etc.

Gas Monitoring Systems

Gas Sensor

Detection gas objects:
Combustible gases (such as methane, hydrogen), toxic gases (such as carbon monoxide, hydrogen sulfide), oxygen concentration, volatile organic compounds (VOCs), greenhouse gases (such as CO₂), etc.

Sensor types:
Electrochemical sensors (detect toxic gases), infrared sensors (detect CO₂, CH₄), catalytic combustion sensors (detect combustible gases), photoionization detectors (PID, for VOCs), etc.

Central Control and Analysis System

Real-time monitoring: Display gas concentration dynamic curve, alarm status and equipment operation status.

Data analysis: Use algorithms to identify gas leakage trends, abnormal peaks or long-term pollution sources.

Automatic control: Trigger linkage devices (such as ventilation systems, emergency shut-off valves).

Data Acquisition and Transmission Module

Collect sensor data in real time and transmit it to the control center via wired (RS485, Ethernet) or wireless (Wi-Fi, 4G/5G, LoRa, NB-IoT) communication.

Support edge computing and perform preliminary data processing (such as filtering and calibration).

Alarm and Safety System

Multi-level alarm mechanism (threshold alarm, trend alarm), supports sound and light alarm, SMS/email notification.

Explosion-proof design (suitable for flammable and explosive environments, such as chemical plants, oil and gas well sites).

User interface and remote management

Local interface: Touch screen or industrial computer displays real-time data.

Cloud platform: supports remote access, historical data query, and generates compliance reports (such as EPA, OSHA standards).

Typical Applications

Industrial Gas Monitoring System

Technical Support

A gas monitoring system, also known as a gas detection system or gas alarm, is used to monitor in real time various flammable and toxic gases that may leak during production, storage, and transportation. A complete gas monitoring system should include components such as gas detectors, a control cabinet (including controllers), switches, and an operation station (including monitoring software).

A gas monitoring system not only issues timely alarms, prompting operators to take emergency measures, but also interlocks the opening and closing of fans and other equipment in the area to mitigate the harm caused by gas leaks.

Sino-Inst primarily supplies gas monitoring systems, including online coal gas analysis systems, metallurgical process gas analysis systems, chemical process gas analysis systems, bio-fermentation process gas analysis systems, online VOC gas monitoring systems, flue gas monitoring systems, and CEMS (Consumer Emission Monitoring System) stationary source flue gas online analysis systems.

Continuous, real-time online monitoring of the oxygen concentration in coke oven gas during the coking process not only provides robust data support for the company’s coking process but also helps mitigate the risk of explosions caused by coke oven gas and excessive oxygen in high-temperature environments.

In addition, by interlocking the online laser oxygen analyzer installed on the coke oven with the pneumatic valve installed on the gas main, this not only saves the manpower and time required to manually close the valve, but also significantly improves the company’s automation level.

The sulfur hexafluoride gas leak monitoring system is linked to the on-site exhaust fan start/stop. When the system detects a significant amount of sulfur hexafluoride gas leakage in the power system’s SF6 room, exceeding the specified concentration or decreasing oxygen concentration, it automatically issues an audible, visual, and screen alarm. The exhaust fan is then forced to start for ventilation. The system automatically shuts down the exhaust fan until the SF6 gas concentration monitoring system detects that both the indoor SF6 and O2 concentrations have returned to normal levels.

The gas monitoring system is used to realize real-time monitoring of gas concentration information, real-time alarm, historical alarm query, historical trend query, historical report, distribution map, SMS alarm and other functions. It is convenient for users to timely grasp the situation of flammable/toxic gases in the environment to prevent explosion and poisoning accidents.

Sino-Inst supplies reliable gas monitoring systems that can be customized according to specific needs. If you need to purchase a gas monitoring system, please contact our sales engineer!
